To provide a pressure foot that can straighten a warp in and preclude floating of a printed circuit board and can move smoothly in all directions.

The pressure foot 5 comprises, basically, a pressure foot body 6, a brush 8 and rolling elements 7. The brush 8 is formed into an annular shape along the lower end edge of the pressure foot body 6. The rolling elements 7 are rotatably embedded in the lower end face of the pressure foot body 6, and at least three of them in spherical form are circumferentially spaced out.
